This pressurized water reactor
style nuclear reactor, built by General Electric,
is designed to have increased energy density, and new plant
components, including a new steam generator design featuring
improved corrosion resistance and reduced life-cycle costs. This
steam generator will alleviate the corrosion concerns encountered
in existing designs of steam generators, while reducing component
size and weight and providing greater flexibility in overall
arrangement.

This reactor is designed to operate for 33 years without
refueling.[1][2]
